Abstract: A method for forming a moving, continuous bed which is composed of granular and/or pulverulent flowable material and which is of constant thickness provides an improved uniformity of the bed by collecting material from a first moving bed so as to form a buffer stock, and by subsequently delivering material from the stock in a regular fashion so as to form a second moving bed which is continuous. An apparatus for carrying out this method comprises a belt capable of being passed through by said material. The material can be moved with the belt over a guide plate situated beneath the belt. In order to prevent too little material being present locally during brief interruptions in the supply of the flowable material and in order to prevent the material being compressed and pulverized in the event of an excessively large supply, a buffer is provided for the material, the discharge opening of which buffer is situated near and above the guide plate. The buffer has an overflow. The material is thus fed via the buffer onto the belt. Provided the buffer remains filled, it is capable of compensating automatically for fluctuations in the material supply.

Abstract: A TECHNIQUE FOR PRODUCING AN EXPERT SYSTEM        FOR SYSTEM FAULT DIAGNOSIS Abstract The present invention relates to a technique for operation on a computer for developing the knowledge base for ultimately providing very fast and cost-efficient fault diagnosis systems. The present technique uses a effective hierarchy of rules where at a first level are rules which allow the arrangement of the system under test to bedecomposed into a hierarchy of sequential and parallel subsystems. At the second level are rules that generate the efficient testing rules for each pure subsystem. The second level rules can be compared to a node evaluation function in a typical problem of searching a graph to select the best node for expansion from a current list of candidate nodes, so that the best path to the correct system diagnosis is found in the shortest amount of time using a minimum of user input. Two heuristic rules are applied tospeed-up the process of selecting the node as the best candidate for expansion. The resultant hierarchy of rules permit the cost-efficient knowledge base and resultant output test tree procedure to be generated for a fault diagnosis system to be applied for testing an associated device or system.

Title: Method for producing sod
Inventor: DECKER HENRY F
IPC: A01G1/00
Filed: 1990-11-19
Granted: 1996-02-13
Abstract: A novel method is described for growing tall fescue sods on a solid base in large rolls.  Whole culm straw is  placed  1-2  inches  deep  over  the  solid  base, typically plastic  sheeting.    Thirty to  forty cubic yards of composted materials are then applied to the straw, filling the voids and interstices to produce a coherent matrix.  This is seeded with tall fescue, then irrigated,  fertilized,  and  mowed  in  a  conventional manner.    Unharvested wheat seed  left  in the  straw germinates  along with the  tall  fescue  and  forms a vigorous primary rooting system which rapidly effects a bona  fide  sod  about  one-half  inch  thick  and approximately one-half the weight of a conventional mineral sod.   The synthetic sod is harvested in large rolls,  typically  as  much  as  five  feet  wide  and comprising 20-50 square yards.   These big rolls are laid at the installation site by the grading tractor, obviating the need for a fork lift, pallets, and laying crew, as used in conventional sodding.

Abstract: A demodulation frequency plan for use in a global positioning system (GPS) receiver, having three demodulation stages for L1 and L2 signal channels, in which identical local oscillator frequencies are used in the L1 and L2 channels at each demodulation stage, to minimize phase error differences between the two channels. The third stage provides an output at an intermediate frequency high enough to carry the full information bandwidth, thereby simplifying digital sampling of the signal, which is also performed in the third stage.      Sampling is performed at a high enough rate to facilitate subsequent conversion to baseband. Moreover, the sampling rate is a binary multiple of the intermediate frequency, and this binary relationship further simplifies conversion to baseband.
